How Many Angels Can Dance on the Head of a Pin? Development of Next Generation Turbodiesel Controls

Abstract

This talk will cover several aspects of the emerging problems faced in diesel engine control development. In particular the interaction of three issues will be considered: (i) increasingly stringent regulation on diesel engine emissions is leading to the introduction of additional hardware subsystems and tighter control performance requirements, (ii) diesel engine powertrains are highly nonlinear plants, with significant multivariable interactions among subsystems, and many different engine layouts are encountered in practice, (iii) the computing environment in modern automotive electronic control units (ECUs) is very restricted with a processor speed is typically slower than 60MHz and only a few MB of flash memory.
